Roll-Up Vent Poly Tunnel Greenhouses Boost Strawberry Yield for East Asian Fruit Farm

Strawberries are a high-value crop that is highly sensitive to rain, humidity and temperature swings. For an East Asian fruit farm, protecting strawberries from the weather while keeping fruit clean and firm was the key to better prices. The grower chose poly tunnel greenhouses from Xiamen Wellgain Greenhouse Engineering Co., Ltd..

The challenge was to protect delicate berries without overheating them on warm, humid days — a balance that depends on ventilation as much as on the covering itself.

Client Background and Challenge

The client supplies strawberries to premium retailers and direct-to-consumer channels. Rain damage, uneven ripening and pest pressure were undermining quality and price. They needed a structure that could:

• Shield berries from rain and reduce disease
• Provide ventilation control on warm, humid days
• Improve fruit appearance and shelf life
• Be installed and maintained affordably

Solution: Poly Tunnel Greenhouses with Roll-Up Vents

We supplied commercial poly tunnels built on galvanized steel frames with UV-treated film and roll-up side vents. The ventilation lets the grower flush humid air quickly, reducing the conditions that cause mould, while the film protects fruit from direct rain and sunlight.

Project Configuration

Results and Benefits

• Cleaner fruit – rain protection reduced mud splash and rot, improving appearance and shelf life.
• Better ventilation control – roll-up vents helped manage humidity and reduce fungal disease.
• Higher marketable yield – more fruit reached premium grade, supporting better pricing.
• Low cost, quick install – prefabricated tunnels were erected efficiently on the farm.

Delivery and Support

Xiamen Wellgain Greenhouse Engineering Co., Ltd. specified the tunnel width, covering and ventilation to suit both the crop and the farm's climate, then delivered a complete prefabricated kit with clear assembly guidance. Optional insect netting was added to further protect the crop during pest season without blocking airflow.

Ongoing Value

Beyond the first harvest, the durable galvanized frames and UV-treated film keep maintenance low, protecting the grower's investment over many seasons while allowing additional tunnels to be added as the business grows.

Why the Project Worked

Matching the right covering and ventilation to a delicate, high-value crop made a clear difference in quality and consistency. Xiamen Wellgain Greenhouse Engineering Co., Ltd. delivered a cost-effective structure customized to the farm's size and climate.
